WEATHER (O. Eng. weder; the word is common to Teutonic languages; cf. Du. weder, Dan. iieir, Icel. vedr, and Ger. Welter and Gewitter, storm; the root is wa- to blow, from which is derived " wind "), the condition of the atmosphere in regard to its temperature, presence or absence of wind or cloud, its dryness or humidity, and all the various meteorological phenomena (see METEOROLOGY). The term " weathering " is used in geology of the gradual action of the weather upon rocks, and is also applied, in architecture, to the inclination or slope outwards given to cornices, string courses and window sills, to throw off the rain.
